Lautering

Syllabus Path

Lautering separates sweet wort from spent grain through mash-out, vorlauf or recirculation, runoff, and sparging. Link runoff behavior and sparging choices to extract, clarity, and tannic mouthfeel.

  1. IV. Beer Ingredients and Brewing Processes
  2. B. Processes
  3. 3. Lautering

Exam Focus

  • Explain lautering as a brewing analysis topic within Processes.
  • Analyze bed formation, vorlauf, runoff, sparge water, flow, temperature, pH, gravity, channeling, compaction, and extract recovery.
  • Balance wort clarity and yield against tannin extraction and stuck-runoff risk when diagnosing or designing a lautering process.

Core knowledge

  • Lautering separates sweet wort from spent grain through mash-out, vorlauf or recirculation, runoff, and sparging.
  • Bed compaction, poor crush, high viscosity, huskless grains, and fast runoff can cause stuck or cloudy runoff.
  • Excessive sparging, high pH, or hot sparge conditions can extract tannins and create astringency.

Study application

Link runoff behavior and sparging choices to extract, clarity, and tannic mouthfeel.

Key Terms

Excessive sparging, high pH, or hot sparge conditions
Excessive sparging, high pH, or hot sparge conditions can extract tannins and create astringency.
